Beren just a little cheap tip , get some 90mm storm water pipe and cut 2x 150mm pieces .
Split theses down the length with one cut only each then you can slide them over the barrels and the tension of the plastic will keep them in place.
The barrels of the 20x80triplets are about 95mm O.D. and 100mm pipe is to large.
Slide them over about 50mm and the 100mm remaining will be the dew shield.
Keep the gap of about 5mm towards the bottom and use tape to cover the gap of the cut if need be.
Of coarse paint them flat black inside.
This will give you 2 removable dew shields and help with the stray off axis light entering the barrels.
If you get these Bino's go to Crazy Clarks or some other discount store and pick up a set of cheap instrument screw drivers.
There about $5-6 from memory.
The collimation screw for the prism is under the rubber plasic cover on top of the prism housing.
You just need to pull the rubber back a touch to access the grub screw.Closest to the eyepieces.
Adjustment is just a matter of a small turn of one or both screws (1/4 turn for example)Don't turn one a lot but do both a small amount in oppisite directions to align the 2 images. Go a little past the best spot and then back a little to get the best alignment. a bit like focusing.
Also try to relax you eyes when doing it by looking away and then back several times.Your brain will merge the images into one if there only slightly out , but this will give you a brain pain in the long run.
